机械工程涉及将能量转化为运动和动力。它涵盖了机械能和热能的产生，转换，传输和使用，并包括设备和系统的设计，构造和操作。当施加力以及加热和冷却时，它还涉及固体，液体和气体的行为。作为机械工程师，您可以从事研发，产品和过程设计，技术销售和支持，制造，现场和测试工程，项目管理，系统设计以及电厂运营和质量控制方面的工作。您可以在石化，汽车，交通，航空，电子，采矿和机器人行业中工作。
Mechanical engineering is about the efficient use of energy in the design and function of all types of mechanisms, from the simplest to the most complex. It builds on engineering principles of physics, chemistry, materials, mathematics and biology to achieve engineering goals.<br>As a mechanical engineer, you might design automatic control systems or take charge of the operation of a smart building. You could manage the water supply for a whole state and design wind turbines or highly efficient, low-cost products for the developing world.<br>In the diverse and challenging field of mechanical engineering, your role as a mechanical engineer could take you into various industries. You might be called on to work with the medical profession to create robots that can operate with greater precision than a human, or be at the cutting edge of advanced manufacturing using 3D printers to create aircraft parts with elegance and function.<br>Growth industries include advanced manufacturing, smart buildings, renewable energy, medical engineering, and consulting practice, where mechanical engineers play pivotal roles.
